PS3, Line 10: - Slowness in TSAN mode along with a low Raft timeout meant 
workloads
            :   would fail to even create tablets.
            :   - Addressed this by increasing the heartbeat interval in TSAN 
mode.
This happens to us quite often. How do you feel about adding a DCHECK or 
something equivalent to enforce that, in TSAN, the Raft heartbeat interval 
isn't below some threshold?

Why don't want to lower the heartbeat interval in this test any more?

PS3, Line 699:     ignore_result(LeaderStepDown(ts_and_details.second, 
tablet_id, kLeaderTimeout));
Should we ASSERT that we succeeded at least once somewhere?
